STRUCT RRADC_CHANNEL(9)

💖 NAME 💖

struct rradc_channel — rradc channel data. Welcome to the Kernel API Manual, bestie; we're about to make this kernel struct make sense, no cap 🫶✨

✨ SYNOPSIS ✨

struct rradc_channel {
    const char *label;
    u8 lsb;
    u8 status;
    int size;
    int trigger_addr;
    int trigger_mask;
    int (*scale_fn)(struct rradc_chip *chip, u16 adc_code, int *result);
};

There she is — the whole struct, every field in place, looking iconic 👑💅

🌸 Members 🌸

• label — the channel label, aka this channel's little name tag 🏷️💖
• lsb — the channel least significant byte — yes, the lsb, she's right there ✨
• status — the channel status address — where the status address lives, periodt 📍
• size — the number of bytes to read — that's the size, bestie, keep it in mind 🔢
• trigger_addr — the trigger address; heads up: the trigger is only used on some channels 🙈💅
• trigger_mask — the trigger mask — iconic little mask behavior 🎭
• scale_fn — a post process callback for channels which can't be exposed as offset + scale — she handles the extra processing for those channels 🧮💜
